To satisfy the demand of high-speed mobile wireless communications, the 5G mobile communication is under developing and the operating frequency is 38 GHz.

To reduce the phase error caused by the inaccuracy of transistor model, this thesis proposes a phase shifter combining the switch type and reflection type phase shifter. With continuous tuning voltage, it can correct the phase error caused by process variation. It can achieve the phase imbalance of less than and the amplitude imbalance of less than 1.5 dB.

The circuit has the advantage of high output voltage ranging from 1 mV to 700 mV without additional op-amp, so it can simplify the circuit design.

碩士 === 國立臺灣大學 === 電子工程學研究所 === 104 === This thesis studies the switch type phase shifters and power detectors. To satisfy the demand of high-speed mobile wireless communications, the 5G mobile communication is under developing and the operating frequency is 38 GHz. Therefore, this thesis chooses this band as the operating frequency of proposed circuits.
This thesis first reviews the architectures of different types of phase shifters and power detectors, and also analyzes the operation principles of these circuits. Considering the application, this thesis chooses switch type phase shifter as main architecture. To reduce the phase error caused by the inaccuracy of transistor model, this thesis proposes a phase shifter combining the switch type and reflection type phase shifter. With continuous tuning voltage, it can correct the phase error caused by process variation. It can achieve the phase imbalance of less than and the amplitude imbalance of less than 1.5 dB.
On the other hand, cross-coupled pair rectifier has been chosen for the first architecture of power detector. The circuit has the advantage of high output voltage ranging from 1 mV to 700 mV without additional op-amp, so it can simplify the circuit design. Furthermore, the cross-coupled pair rectifier is integrated with an on-chip antenna. It can not only reduce the transfer loss between rectifier and antenna but also reduce production costs.
